Its primary goals are to increase file system performance, as well as adding full system call compatibility. WSL 2 uses an entirely new architecture that uses a real Linux kernel.

If Windows is to support developers building Linux apps for the cloud, then it needs to be more than consistent, it needs to be compatible. The Linux kernel in WSL 2 is built in house from the latest stable branch, based on the source available at kernel.

This kernel has been specially tuned for WSL 2. It has been optimized for size and performance to give an amazing Linux experience on Windows and will be serviced through Windows updates, which means you will get the latest security fixes and kernel improvements without needing to manage it yourself. File intensive operations like git clone, npm install, apt update, apt upgrade, and more will all be noticeably faster.

Initial versions of WSL 2 run up to 20x faster compared to WSL 1 when unpacking a zipped tarball, and around x faster when using git clone, npm install and cmake on various projects.

The Ubuntu In addition to looking at the WSL1 vs. WSL2 performance of Ubuntu Linux binaries use system calls to perform many functions such as accessing files, requesting memory, creating processes, and more. In WSL 1 we created a translation layer that interprets many of these system calls and allows them to work on the Windows NT kernel. Now that WSL 2 includes its own Linux kernel it has full system call compatibility. This introduces a whole new set of apps that you can run inside of WSL.

Using WSL 2 means you can also get the most recent improvements to the Linux kernel much faster than in WSL 1, as we can simply update the WSL 2 kernel rather than needing to reimplement the changes ourselves. WSL 2 will be a much more powerful platform for you to run your Linux apps on and will empower you to do more with a Linux environment on Windows. To test WSL 2 performance I have measured a Ruby on Rails application bootstrap time and the results were quite disappointing:.

Add linux rootfs folder to windows defender exclusion list 2. I have done a study on latest WSL2 performance compared with Ubuntu I wrote this article when WSL is in windows insider preview only.

Ask Ubuntu is a question and answer site for Ubuntu users and developers. It only takes a minute to sign up.

I would like to ask a question about testing a large CAE simulation on the same computer in the following two situations. Your simulation software is most likely either CPU bound or memory bound. For such workloads, one would not except to see any significant difference between running the code on "bare metal" or inside WSL or any other compatibility layer or VM that uses native executionsince in either case the OS is mostly just standing by while the simulation code runs directly on the CPU.

If yours is, you may want to consider running it from a RAM disk e. In any case, the only way to be sure is to test your simulation in both environments and time how long it takes to run. Before doing that, however, you may want to take a look at existing benchmarks, like this WSL vs.

VirtualBox vs VMware Performance Comparison 2019

Docker vs. VirtualBox vs. One potentially relevant issue that I failed to note above is that the benchmarks show significant differences in multi-threaded OpenMP performance both between the different host environments and also between different Linux distros even when running on bare hardware. In hindsight, that's not too surprising, since threading and IPC is handled by the kernel. If your software doesn't specifically require native Linux filesystem features like multiple hard links to the same file, configuring it to store its data files in a DrvFs folder may improve file access performance on WSL.

Unless something has changed over the last year, this presumably means that using tmpfs on WSL gives no performance benefit over using a normal on-disk filesystem. For example screen painting takes many times longer in Windows 10 versus Ubuntu It takes about 5 seconds for the WSL Bash splash screen to paint. On Linux about 24 seconds on Windows 10 version about 31 seconds.

However I just upgraded Windows 10 to version Redstone 4 aka Spring Creators April update and it took 24 seconds which is the same as Linux.

WSL2: Code faster on the Windows Subsystem for Linux! - Tabs vs Spaces

NOTE: Windows 10 spring update for dubbed Redstone 4 came out on May 9th 4 days ago and I will be installing it soon to check out the improvements.

No doubt there are many. One I know of that interests me is the ability to run cron jobs on startup. I need that for automatic daily backups to gmail. It's now only 3 seconds instead of 5 seconds to display the Bash splash screen. The CPU benchmark is on par with Linux now. Think about it - in WSL your computer is running the full graphical Windows system which is a horrific resource hog in the first place plus the Ubuntu subsystem.

In native Ubuntu it's only running Ubuntu. And the performance penalty comes from several layers:. Ubuntu Community Ask! Sign up to join this community. The best answers are voted up and rise to the top.

Viewed 8k times. Zanna Without knowing the nature of the simulation, this is impossible to answer. A "simulation" is presumably a computationally intensive background job, which makes it either CPU or memory bound.

One could pretty easily write or download a benchmark that tests all these 2 to 5 possible bottlenecks, and check if there's any significant difference between WSL and native Ubuntu for any of them.

I have enabled the VirtualMachinePlatform as instructed, but I am still unable to upgrade my distribution to version It is required for docs. Same issue here. I hope that is not the case. I solved it on my PC.

But if you open it with Powershell, system won't check if "Virtualization" option is set to enabled. Enabling virtualization appears to be working on my system; I can't believe I didn't think of doing that. Is there another way to enable virtualization or am I out of luck while using Home Edition? I apologize if there is a simple fix for this, I am new to Windows. Before the fix, Bash shell command uname says it's running Linux 4. I guess that's what the MS system call emulator call itself.

Did anyone get any easy fix? I fix it by launching both commands in an admin terminal. Use another session cause error message appear. I've already enabled VirtualMachinePlatform feature and rebooted. CPU has virtualization extensions enabled. Yet, wsl is not a valid command. I did install Microsoft-Windows-Subsystem-Linux but this appears to be v1. Unable to execute WSL commands as the flags --set-version and --list --verbose are unknown i tried to upgrade to WSL2 right after finishing the system upgrade to Version This thread is for the specific issue of seeing the error 'Please enable the virtual machine platform' when it is already enabled, and we're working on resolving that error.This architecture will be available in the 'Virtual Machine Platform' optional component.

This optional component will be available on all SKUs. You can expect to see more details about this experience soon as we get closer to the WSL 2 release. We currently have no plans to deprecate WSL 1. You can learn more about VirtualBox's changes here and VMware's changes here. We are investigating ways to help resolve this issue.

This lets applications use the Hyper-V architecture for their emulation such as the Google Android Emulatorand VirtualBox 6 and above which are both now compatible with Hyper-V.

In initial releases of WSL 2 hardware access support will be limited, e. However, adding better device support is high on our backlog, as this opens many more use cases for developers that wish to interact with these devices.

In the meantime, you can always use WSL 1 which has serial port access. Yes, in general networking applications will be faster and work better since we have full system call compatibility. However, the new architecture uses virtualized networking components. This means that in initial preview builds WSL 2 will behave more similarly to a virtual machine, e. We expect to add improvements as quickly as we are able to, such as accessing all networking apps from Linux or Windows using localhost.

We will be posting more details about our networking story and improvements as we approach the release of WSL 2. You need to make sure that the virtual machine has nested virtualization enabled. This can be enabled in your parent Hyper-V host by running the following command in a PowerShell window with Administrator privileges:.

WSL 2 supports the same wsl. This means that any configuration options that you had set in a WSL 1 distro, such as automounting Windows drives, enabling or disabling interop, changing the directory where Windows drives will be mounted, etc.

You may also leave feedback directly on GitHub. Skip to main content. Exit focus mode. Will it be available on Windows 10 Home? What will happen to WSL 1? Will it be abandoned? Are there plans to increase hardware support? Will WSL 2 be able to use networking applications?

I work in IT mostly desktop support and network administration in a Windows environment, and I occasionally program. A couple weeks ago, I decided I couldn't be as effective as I want to be without a Bash environment for my command prompt needs.

This is especially true when I am using Ruby and git. I used Msysgit for a while, but I just didn't like how it wasn't extensible like Linux. So, I installed Cygwin and played around with that for a couple weeks. As great as Cygwin is, it seems like it is meant to be a suped up command prompt, and its compatibility with Linux is just a pleasant side effect.

This especially became evident when I tried to upgrade Ruby to 1. So, now I'm considering running Linux in a virtual machine. But I'm worried that might be another can of worms and I'll have wasted hours before I find that out.

But I don't like that support for it is not as thorough as for a major distro. I have faced common issues before, and the best solution according to my experience is just 2 workstations :. Apart from that having Linux running in a virtual environment is way better.

First of all, you will have full Linux capabilities except 3d acceleration, but you probably don't need that.

wsl2 vs virtualbox performance

You will have the capability of creating snapshots and revert back to them when things go wrong! You can start multiple environment using templates, which is very convenient. The only downfall I can think of is performance issues of the host machine.

For something tightly integrated and some "real" word, go to a vm. It will emulate everything and separate development from the real machine, and this may be a good thing in some cases Then you can use that "entry point" to symlink stuff into the vm, and do the things you need with the real files being located in the real host machine.

There is something I have heard of called Cooperative Linux. It runs Linux alongside with Windows kernel so you can use them at the same time. What I think now is getting the pros of 2 options is using Dockerit is giving you cygwin simplicity and VM functionality with better performance.

Linux in a virtual machine will give you the experience you want more than cygwin or any mock shell as I like to call them. Running VM's though require a lot of ram depending on whether you want a desktop version of linux or just a command line version.

Myself in work I have a pc with 8gb of ram and I run ubuntu 64bit as main OS, two ubuntu servers these are for dev environments two different projects and a windows 7 VM and a win XP VM.Changes in this new architecture will allow for: dramatic file system performance increases, and full system call compatibility, meaning you can run more Linux apps in WSL 2 such as Docker. Our top requests from the WSL community have been to increase the file system performance, and make more apps work inside of WSL i.

We have heard your feedback, and are glad to announce that WSL 2 helps solve these issues. WSL 2 uses an entirely new architecture that uses a real Linux kernel.

Yes, you did just read that heading correctly! We will be shipping a real Linux kernel with Windows that will make full system call compatibility possible. However, this will be the first time a Linux kernel is shipped with Windows, which is a true testament to how much Microsoft loves Linux! In initial builds we will ship version 4. This kernel has been specially tuned for WSL 2.

It has been optimized for size and performance to give an amazing Linux experience on Windows. We will service this Linux kernel through Windows updates, which means you will get the latest security fixes and kernel improvements without needing to manage it yourself. Lastly, of course this Linux kernel will be fully open source! When we release WSL 2 we will have the full configuration available online on Github, so you can see how it works and build it yourself.

WSL 2 uses the latest and greatest in virtualization technology to run its Linux kernel inside of a lightweight utility virtual machine VM. When you think of a VM, you probably think of something that is slow to boot up, exists in a very isolated environment, consumes lots of computer resources and requires your time to manage it.

WSL 2 does not have these attributes. It will still give the remarkable benefits of WSL 1: High levels of integration between Windows and Linux, extremely fast boot times, small resource footprint, and best of all will require no VM configuration or management.

When we start our distro we get access to a working bash shell in under two seconds, and can run services and apps like docker right away. You can expect more detail on the exact changes to the architecture posted to this blog in the near future, so please stay tuned! File intensive operations like git clonenpm installapt updateapt upgradeand more will all be noticeably faster.

Linux binaries use system calls to perform many functions such as accessing files, requesting memory, creating processes, and more. In WSL 1 we created a translation layer that interprets many of these system calls and allows them to work on the Windows NT kernel.

But I'm talking about using it directly on Windows So I will appreciate any information about these two. WSL1 took an approach of adding a Linux syscall compatible layer at the top of the NT kernel, allowing Linux binaries to run atop NT, sharing the same underlying filesystem, networking, process list, etc.

This is, Docker's preferred and future path for running Docker on Windows desktop. That is correct. Ubuntu Community Ask! Sign up to join this community.

Installing docker for Windows 10, and use a container with Ubuntu. I'm no expert in any of them to write an answer, but my vote goes to Docker. The reason is that Docker implies virtualization, so things should just work.

WSL on the other hand is full of bugs. It does work for benchmarks, fun, and mostly development; but if you're about to deploy something serious, this is not your choice, at least not yet.

I'm wiping windows 10 off of here and installing ubuntu You don't need to be toxic, especially at the end.

Rather, please tell us what you did to research the cause of the problems you're facing and whether they are known issues or not and if someone is working on fixing them or not. I'm sure they are though. And you don't need to uninstall windows, you just need to install hyper-v manager and quick install Ubuntu and you're set for a Linux development environment if you want to work from inside a virtual Linux Desktop.

Otherwise keep using WSL and wait for your issues to be fixed. AFAIK the speed issues are related to Windows file access subsystem and a workaround is in the works. WSL still seems slow.
